Abstract

As a key infrastructure in the power industry, substations play an important role in achieving the strategic goal of “dual carbon”, and their sustainable development concept radiates to the entire field of structural buildings and ecological buildings. Based on a systematic review and in-depth analysis of carbon emissions across the entire life cycle of substations, this paper, in combination with the characteristics of substation projects, analyzed the boundaries for carbon emission calculations and carbon emission accounting methods. It calculates the carbon emissions over the entire life cycle and compares and analyzes the carbon emissions under different structural forms. The study finds that the carbon emissions during the operation phase dominate, accounting for as much as 54% in the entire life cycle of substation. Furthermore, steel- structured substations reduce carbon emissions by approximately 10% compared to concrete structure substations. Considering energy conservation and emission reduction comprehensively, steel structure substations are superior to concrete structure substations. The research results not only provided strong data support and theoretical basis for the low-carbon design, construction and operation of substation, but also contributed to the energy conservation and emission reduction in the construction industry, civil engineering and hydraulic engineering field.
